In addition to the article link, Grisham referenced a White House event set for Tuesday afternoon for which Trump is "hosting children at the White House … to talk to them about kindess." She asked Lassner, "should I save you a seat?"

The White House announced on Monday that the first lady would be hosting 30 sixth-grade students for a 3 p.m. screening of the movie "Wonder" in celebration of National Bullying Prevention Month and to show "the importance of choosing kindness."

Lassner hit back soon after Grisham's tweet to not only accept her invitation but also reference past Trump administration controversies.

Lassner's mention of President Donald Trump's expressed doubt to whether former President Barack Obama was born in the United States and of a jacket the first lady wore to visit detained immigrant children that said, "I really don't care, do U?" prompted Grisham to tell him to "check your facts before you get here" and that she would be "happy to brief you upon arrival."

The producer's latest reply included a 2011 HLN interview in which Trump pushed her husband's questions about Obama's birthplace and blamed "the media" for focusing on the issue.

Grisham has ramped up her vocal defenses of the first lady after recent controversies, including furor over a hat she wore during her tour of African countries that many took as an offensive symbol of colonialism.

In a statement to INSIDER about the incident, Grisham said Trump is "working to help children all over the world through her Be Best initiative," which focuses on childhood well-being, social media use, and opioid abuse.

She continued: "The people who consistently attack her — the left-wing media and Hollywood elites — could be so effective in helping to spread her message of kindness, but instead they choose to attack her because of politics. It does nothing but spread bias and hate, and it needs to end."
